Abstract (en)
[origin: US2012011981A1] A method of forming a scribe line in a strengthened glass substrate includes providing a strengthened glass substrate having a first surface, a second surface, a first edge and a second edge. The first and second surfaces have a strengthened surface layer under a compressive stress, and a central region under tensile stress. The method further includes applying a scoring blade to the first surface at an initiation location that is offset from the first edge by an initiation offset distance greater than a diameter of the scoring blade, and translating the scoring blade or the strengthened glass substrate such that the scoring blade scores the first surface. The translation is terminated such that the scoring blade stops at a termination location that is offset from the second edge of the strengthened glass substrate by a termination offset distance greater than the diameter of the scoring blade.
